    • Step 5: Selecting and implementing the best solution using a predictive or agile approach.
    • Step 6: Evaluating the implemented solution, adjusting as necessary, and learning from the experience.

    PDCA Cycle

    • The Plan-Do-Check-Act (PDCA) cycle is a management process used for continuous improvements in products and processes.
    • The cycle begins with planning objectives for improvement, and includes considering risks and developing planned steps for implementation.
    • The Do stage involves implementing the steps and carrying out the planned improvements, while monitoring the steps.
    • Measuring, analyzing, and evaluating the effectiveness of the improvement comes in the Check phase.
    • The Act phase, which completes the cycle, involves optimizing the performance and implementing changes.

    Brainstorming

    • Brainstorming is a technique for generating creative ideas and potential solutions to a problem.
    • A facilitated group process is essential for generating numerous ideas.
    • Brainstorming is effective when used in group settings to draw upon the combined experiences and creativity of all members.
    • Effective brainstorming allows participants to explore new ways of looking at things and freely associate in any direction.

    Reverse Brainstorming

    • Reverse brainstorming combines brainstorming and reversal techniques to generate solutions to a problem.
    • This technique encourages asking "How could I possibly cause the problem?" instead of "How do I solve the problem?".
    • The goal is to identify solutions to a problem by taking the opposite approach.

    Steps in Reverse Brainstorming

    • Clearly identify the problem.
    • Reverse the problem by asking questions like "How could I possibly cause the problem?".
    • Brainstorm possible solutions to the reversed problem.
    • Reverse the solutions from the first brainstorm session back to the original problem.
    • Evaluate the potential solutions.

    Decision Analysis - Decision Matrix

    • Decision analysis evaluates potential decisions, based on different outcomes to determine the best option under conditions of uncertainty.
    • Various tools like a decision matrix can be used to make decisions.
    • These tools objectively evaluate a variety of criteria and factors for the analysis, looking at factors such as cost, risk level, ease of implementation, and acceptance.
    • Used to assess solutions, the decision analysis assists in decision-making under various situations like choosing the most cost-effective option, weighing risks vs. rewards, and selecting the solution that best satisfies various needs and criteria.

    Simple Decision Matrix

    • Simple decision matrices are decision-making tools that allow the assignment of equal weight to various criteria in the evaluation process.
    • These tools provide straightforward evaluation systems of possible solutions.

    Weighted Decision Matrix

    • The Weighted Decision Matrix allows unequal weighting of the various criteria which can be assigned.

    PERT Average

    • The PERT average is a technique for estimating values.
    • Experts' opinions are used to find the weighted average of given parameters.
    • The method involves collecting data on the lowest (L), middle (M), and highest (H) values from different experts.
    • Calculation utilizes the formula: (L + 4M + H) / 6

    Assigning Weights to Criteria

    • Weights for criteria can be assigned based on perception, expertise, and situational context.

    Analytic Hierarchy Process (AHP)

    • AHP is a rational framework to quantify criteria and alternatives for decisions.
    • This method is used for decision-making by determining qualitative criteria weighting.
    • AHP prioritizes criteria using pairwise comparisons, with experts providing input and using PERT averages to obtain scores for each criteria.

    Pareto Chart

    • A Pareto Chart is a quality control tool.
    • This chart combines a bar graph and a line graph to identify areas needing improvement.
    • The chart helps prioritize potential solutions to problems, often utilizing the 80/20 rule to identify the critical few issues that generate most of the effects/results.

    Five Whys

    • The Five Whys is a problem-solving technique that repeatedly asks “why” to determine the root cause of a problem.
    • This technique focuses on the cause of the problem.
    • This technique can be used on its own or in conjunction with other tools such as the fishbone diagram.

    Steps to Use Five Whys

    • Steps for the Five Whys technique:
    • Write the problem down.
    • Start asking "why" repeatedly
    • Continue asking "why" until the issue is determined to fully meet the needs of the question.

    Usage Considerations of Five Whys

    • Benefits of the Five Whys include maintain an objective view, determine solutions, and pinpoint the origin of issues.
    • Limitations include the need for well-trained users to ascertain the actual root cause and the possibility of the technique leading to false or irrelevant conclusions if complex issues are involved.

    Root Cause Analysis

    • Root cause analysis is a systematic process utilized to analyze situations and problems.
    • It focuses on identifying the root causes for issues rather than only examining their effects.
    • The method involves systematically analyzing factors that lead to the effect.
    • Methods for root cause analysis include cause-and-effect diagrams, brainstorming, five whys, and others.

    Fishbone Diagram

    • Fishbone diagrams (Ishikawa diagrams) are tools used for cause-and-effect analysis.
    • This method helps to identify and organize possible causes for a problem.
    • The diagram visually depicts potential cause-and-effect relationships to help organize analysis of potential solutions.

    Risk Analysis and Management

    • Risk analysis and management identifies and examines areas susceptible to negative impacts on business and identifies potential solutions.
    • The method identifies, evaluates risks, and generates response plans.
    • Techniques to help identify risks includes using past experiences, expert judgment, and historical analysis.

    Risk Identification

    • Risks are discovered through multiple methods, such as expert judgment and historical data analysis.
    • Identify potentially negative impacts and consequences from any occurrences.

    Risk Analysis

    • Understanding the risk, assessing likelihood, and estimating the impact are key components of this phase.
    • Risk analysis involves determining the likelihood of risk events occurring, as well as the impact they might have if they happen.

    Risk Evaluation/ Assessment

    • Evaluating risk analysis results against the value of the change or solution.
    • Analyzing risk factors and likelihoods, such as cost, duration, and social impact.

    Risk Treatment

    • Some risks may be acceptable; others require actions to reduce them.
    • The approaches include avoiding the risk, transferring the risk to a third party, mitigating the risk, accepting the risk, or increasing the risk to achieve an opportunity.
    • The risk treatment plan is created, a risk owner is identified, and the plan ensures the best approach is taken to reduce risk to the lowest possibility.

    Continuous Risk Identification/ Assessment

    • This continuous process reevaluates risks after implementation of plans to reduce risks and improve solutions.
    • Risk reevaluation is an ongoing process to accommodate changes and the new residual risk levels once action plans are put in place.

    SWOT Analysis

    • SWOT analysis is used for evaluating organizational strengths, weaknesses, and external opportunities and threats.
    • It helps in understanding the organization and enabling it to identify factors like personnel, processes, and external conditions.
    • A SWOT analysis can be conducted for an entire organization, or divisions, departments, projects, or even individual employees.
    • The technique uses data and analysis of external and internal factors, resulting in a better understanding.

    Reviews

    • A review is done to evaluate the content of a given work product.
    • Reviews help to create a higher quality product.
